Specification of Letters Patent.

Application filed July 31, 1911.

Patented Aug, 1914. Serial No. 641,624.

To all whom it may concern Be it known that I, BARCLAY WHITE, a I

citizen of theUnited States, and a resident of Lansdowne, Delaware county, Pennsylvania, have invented certain Improvements in Supporting, Spacing, and Reinforcing Means for Concrete Construction, of which. the following is a specification.

My invention relates to reinforcing means for concrete construction of floors, walls, ceilings, slabs, &c., and the object of my invention is to provide means for supporting and spacing in their proper position the reinforcing rods employed in such concrete construction, and by the same means furnishing reinforcement in a direction approximately at right angles to the support ed and spaced rods. 1

A further object of my invention is to provide retaining means for securing the reinforcing rods to the supporting and spacing means to prevent dislodgment or separation at the crossing point, and a still further object is to provide locking means for the rod'retaining means-..

The reinforcing, supporting and spacing means forming the subject of my invention comprises a strip or bar of metal having integral supporting elements struck up there from, with retaining means for the reinforcing rods adjacent said supporting elements; such strip or bar being disposed substantially at right angles to the reinforcing rods and forinii'ig part of the reinforcementsubstantially at right angles to the same.

These and other features of my invention are more fully described hereinafter, refer- I ence being had to the accon'ipanying drawings, in which:

Figure 1, 1s a plan view of a blank from,

which one type of supporting'and spacing element within the scope of my invention may he formed; Fig. 2, is a perspective view illustrating a supporting and spacing member formed from the blank shown in Fig. 1; Figs. and 4-, are plan views illustrating other forms of blanks from which supporting and spacing elements within the scope of .my invention may be made; lligsuti and 6, are perspective views'illustrating modified forms of supporting and spacing elements Within the scope of my invention made from the blanks shown in igs. '3 and 4; Fig. 7, is a side elevation of the support-- ing member shown in Fig. 2, employ d f slightly diii'erentmanner; Fig. 8, is a plan view illustrating a further modification within the scope of my invention; and Fig. 9, a view, similar to Fig. 7, showing a further modification within the scope of my invention.

The structure shown in Fig. 1, comprises strip or bar of metal, a'metal band for instance, indicated at 1., which may be, appronimately, an inch, or an inch and oneeighth, or any other convenient dimension, in width, and approximately one-eighth or one tenth of an inch, or any suitable proportion, in thickness; having one side cut as indicated by the lines 2 and '3, to form ortions a, which may be bent substantlally upon the dotted lines 5, approximately at right angles to the strip 1, to provide supporting means, Simultaneously with the formation of the cuts 2 and 3 and the bending of the portions 4: to form the supporting means, corners 6 adjacent the cuts 2 of said main strip 1 are bent down as indicated,

forming shoulders or hooked elements projecting slightly below the plane of the under surface of the strip 1, which shoulders or hooked elements serve to engage retainingmeans in the form of wires 7, extending across the strip 1, and over reinforcing rods 8, positioned over the supporting means 4;. hen thus arranged, the supporting and spacing members may be disposed approximately two feet between the centers, or at any other convenient or desired distance, while the reinforcing rods, mounted on top of said supporting and spacing members, may be spaced approximately six'inches between centers, or at any'other convenient or desired distance.

In Figs. 3, 4, 5, and 6, l have shown modified constructions in which the reinforcing rods suspended from the supporting and spacingmembers. In Figs. 3 and 5, portions 4 are cut from the strip 1 at opposite sides of the same, and in'the cutting operation notches 9 may be formed in said strip adjacent the cuts 2* to form hooked retaining elements,,vvhi1e said portions 4 may be formed with projecting portions or shoulders 10. When wires 7 are applied to clamp the reinforcing rods to the supporting and spacing members, the ends of said wires engagethe notches 9 and are retained by the hooked elements against movement. The shouldered portions 10 directly underiie the wires 'F so that if, in the assembly cated at 4 being bent over the reinforcing rod in the form of a hook to retain the latter in place. A further modification may consist in disposing portions 4 cut from the strip 1 on opposite sides of the same, to form supporting and retaining means, as indicated'in Fig; 8. The corners 6 in each instance being-also bent down to provide hooked elements for. retaining the wires 7 employed to confine the reinforcing rods in place.

In some instances it may be desirable to employ the supporting and spacing means in the manner illustrated in' Fig. 7, but with.

the full value of the supporting legs 4, and in such instance I provide a structure of the type illustrated in Fig. 9, in which a retaining strap or hook 4 for the reinforcing rod or bar is bent fromthe metal strip on the side-opposite that from which the supports 4 are bent. p Although I have shown flat strips or-bars of metal providing the supporting, spacing and reinforcing means, from which the integral supporting elements or legs may be pressed up, it will be understood that other shapes may be employed, if desired; that is to say, angle or L-shaped sections, as well as T-sections. In the latter instance it is practicable to form the supporting elements or legs 4 alternately on opposite sides of the central web, which is preferably disposed on the under side of such form or support. While I have referred more particularly to the use of my iinproved supporting and:

spacing means in connection with reinforcing rods or bars employed in floor, ceiling and slab construction, it will be understood that it may be employed with equal value, ease, andfacility, for supporting the reinforcing rods or bars used in wall or roof construction.

It will be understood, of course, that other modifications within the scope ofmy invention may be made, and my claims are intended to cover the same.

I claim:

1. A supporting and spacing means for reinforcing rods comprising a strip whose body portion is continuous in one plane having supporting portions displaced therefrom at intervals whereby Walls laterally disposed with respect to the strip are formed in the body portion, andlmembers engaging said walls and bridging saidrods for confining the latter to said strip.-

I 2. 'A supporting and spacing means for reinforcing rods comprising a flat strip whose bodyportion is continuous in one plane having portions displaced therefrom at intervals forming integral depending legs where by walls are formed in the body portion of said strip at an angle with respect thereto, and independent members engaging said Walls and bridging said rods for confining the latter to said strip.

8. Supporting and spacing means for reinforcing rods comprising a strip of mate rial having its edges notched, the portions displaced in providing such notches being bent downwardly to form integral legs and the notches having walls at right angles to the length of the strip, and independent.

forming walls at an angle with respectto the strip, the material displaced depending from said strip in the form of integral legs, reinforcing rods or bars carried by said supporting and spacing means, said elements being disposed substantially at right angles to each other and the supporting means being proportioned to afford a reinforcing value, and

means engaging the walls adjacent the struck up portions for confining the elements together.

6. The combination with supporting and spacing means for reinforcing rods comprising a strip of materlal having integral feet depending therefrom, said feet being formed by displacing portions of said strip, a series of reinforcing rods, and independent retaining means for confining said rod to said strip of material, said retaining means engaging the walls of the openings formed by cflisplacing the portions forming the integral eet..

7. In supporting and spacing means for reinforcing rods, the combination of a metal strip disposed at right angles to said rods, legs integrally connected to said strip, a reinforcing rod, a retaining wire for said rod, and hooked elements carried by the strip for confining saidawire in position.

8. In supporting and spacing means for reinforcing rods, the combination of a metal element disposed at right angles to said rods, legs integrally connect-ed to said element, a reinforcing rod mounted on said element, a retaining ine for said rod, and downwardly projecting hooked elements carried by the metal element for engaging the ends of said Wire to hold the same in position.

9. The combination, in reinforcing means for concrete construction, of a plurality of reinforcing rods extending in one direction, a plurality of metal elements disposed at right angles to said rods, integral supporting members for said metal elements, the latter having shouldered projections. adjacent the supporting members, and Wire members having their ends caught by said shouldered projections for retaining said reinforcing rods to the metal elements.

In testimony whereof, I have signed my name to this specification, in the presence of tWo subscribing Witnesses.
